The grind is quite consistent and the grinder only produces few fines-

Workshop

Notes from our brewing workshop. Will be updated. Please use the evaluation form.

Part 1: What is specialty coffee?

Specialty vs Commodity

  • Not a standard flavor (Single origin > Blend)
  • Variety > Uniformity
  • A fascination with coffee as a fruit
  • Strict definition: A coffee that scores more than 80 on the cupping form

Arabica vs Robusta

Processing: Washed, dry and honey

Roasting

  • Identifying: Light, medium, dark
  • Underdevelopment: Why it occurs

Cupping + the cupping Form

  • Flavor wheel
  • A note on the avant-garde in both coffee and music

Part 2: Brewing

Beans & Regions

  • Most specialty coffee comes from either typica or bourbon. One major exception is Ethiopian heirloom.
  • Ethiopian Heirloom: Lemon, blueberry, peach, bergamot
  • Kenyan Sl 28+34: Apple, raspberry, umami
  • Latin American: Sweet, clean: Fruits, berries,
  • Indonesia: Wet hulling: Earthy, woody, mushroomy
  • Brazil: Pulped Natural: Chocolate, nuts, round, lack of acidity
  • Southeast Asia: Chocolate, nuts, hints of lemon. Catimor influence is a drawback. Often the best coffee is natural processed or honey.
  • Panama Geisha: An Ethiopian coffee grown in Panama

Other things that influence flavor

  • Varietal
  • Processing
  • Altitude
  • Aging
  • Storage

Ratio

  • 1:15 – 1:18 typical brew ratio
  • Espresso 1:2 / 1:3 (depending on country and style – ristretto/espresso)
  • Note: That with espresso ratio refers to the liquid after the shot is pulled, while brew ratio refers to the relation between bean and water before brew when we’re talking French press, drip etc.
  • Tip: Always use a scale. It’s very difficult to eyeball

Extraction

  • How much you extract depends on several variables: Grind fineness, temperature of the water, contact time, pressure.
  • Different compounds extract at different rates.
  • Best practice: 18-22%
  • But all coffees are different – adjust accordingly

Methods, techniques, recipes

  • We focus on pour over with the Hario V60. There are many different recipes and schools of thought.
  • The 4:6 method (invented by Tetsu Kasuya) works well with cheaper grinders.

What you need

  • Grinder
  • Water
  • (must not be too hard or too soft. Ideally, between 50-100 TDS. Try different bottled waters, experiment with RO water + mineral mix, or Brita Pitcher)
  • Brewing device (+ filter): Always use white filters. Go for a filter with a rough texture if possible.
  • Gooseneck Kettle

Tasting

Brew in a server, swirl and aerate, drink from glass or ceramic cup at an appropriate temperature.
